Overview
OmniAcetal is a premium-grade POM-C copolymer acetal designed for demanding engineering applications that require excellent dimensional accuracy, consistent mechanical performance and low moisture sensitivity. With a dense and porosity-free structure, OmniAcetal ensures stability in wet and humid environments and exhibits a low coefficient of friction. It combines strength, stiffness and machinability with high resistance to wear and fatigue. These properties make it highly reliable in precision applications such as gears, guides and valves, especially in the food, packaging and medical industries.
